Weekly review / event-driven updates

Civil Resilience, not a humanitarian emergency. Taiwan's civilian systems are functioning; what this surface measures is dependency, exposure and preparedness, not need.

AssessmentModerate confidence

Broad regional level only. This surface never maps aid routes, facility locations or operational detail. Figures are national-level government, agency and research statements, each carrying its own basis and vintage. This module publishes no shelter locations or capacities, no emergency procedures, no critical-infrastructure siting, no cable landing points or routes, no evacuation planning, no continuity-of-government detail and no casualty, duration or scenario modelling. Where a figure could be operationally useful at finer granularity, it is stated coarsely or omitted.

Current state

Where the civilian systems stand

Moderate confidence · Data as of 2026-09

No humanitarian emergency is under way in Taiwan, and none is forecast here. What this surface measures is dependency: an island of 23 million that imports almost all of its energy and roughly seven-tenths of its calories, reaches the world through fifteen international undersea cables, and runs civilian systems that pressure would touch long before anything military did. Vigil treats resilience investment as the most informative material in the file, because it is public, dated and measurable, while the scenarios it guards against are none of those things. Three distinctions do more work here than any figure: announced is not delivered, tested is not effective, and redundancy is not immunity.

How the systems rest on each other The dependencies this module states between its own systems. A relationship, not a consequence — what a disruption would actually do is an impact chain, and only where the corpus establishes one.

An edge says one system rests on another. It is not a failure cascade: it carries no magnitude, no sequence and no timing, and nothing here says what happens when a system is disrupted. Where the corpus establishes that, it is an impact chain with its own stages and its own per-step basis grades, linked from the system itself.

Sheltering and movement — planning, not displacement

As of 2026-08

Nothing in this object describes displacement. Taiwan has none, and importing the vocabulary of active-war modules would be the single easiest way to make this surface dishonest. What it describes is planning capacity and a structural constraint. The planning is real and exercised: the August 2026 urban-resilience component ran local emergency operations centres, relief centres, medical stations and supply distribution hubs at physical sites, and the ADMA handbook directs the public to shelter-locator tools rather than to routes. The constraint is geographic and is the reason this object cannot be modelled the way a land-border crisis is: an island has no border to cross, departure would depend on the air and sea links a crisis would itself disrupt, and the nearest receiving states — Japan and the Philippines — would face the arrival problem alongside their own exposure. Regional discussion exists at official and research level; no public framework is established. The practical resilience question here is therefore the domestic one — whether people can shelter in place with supplies, information and services — which is why this object depends on every other object on this surface. Vigil publishes no shelter location or capacity, no evacuation routing, no scenario modelling and no population-movement estimate.

What this does not establish

  • Shelter capacity, siting and sufficiency are not published and are not assessed here.
  • No public regional framework exists for large-scale departure, and no receiving-state planning is on the record.
  • Household preparedness is surveyed and consistently modest, but no public measure connects survey responses to behaviour.

Water — catchment, storage and who gets it first

As of 2026-06

Taiwan's water system is a short-storage system on a steep island: high annual rainfall, concentrated in typhoon season, held in reservoirs that silt and drain quickly, supplying households, agriculture and an industrial base whose largest users sit in the same western corridor as the smallest catchments. The 2026 dry season tested it. Western Taiwan recorded its driest winter in 75 years — reservoirs south of the Hsinchu–Yilan line took between 7 and 37 per cent of the prior year's rainfall for the period — and from late March the Water Resources Agency ran a staged response through July: overnight mains-pressure reduction, voluntary industrial reductions of up to about 7 per cent, and inter-basin transfers including a reported 232,000 tonnes a day into Hsinchu. Zengwen reservoir was at 28.5 per cent of capacity in late March. Supply held: by 11 June the agency reported about one month of safe storage and expected stability through September. Two things follow, and only two. The response worked in 2026 because transfer infrastructure built under the Forward-Looking programme existed — and ten of sixteen major pipeline projects in that programme were still incomplete in June 2026. And water is a downstream dependency of power: treatment and pumping run on the grid, which is why a power event becomes a water event without anything touching the water system itself. Desalination capacity for Hsinchu and Tainan is planned rather than in service. Vigil publishes no reservoir-by-reservoir operating detail and no estimate of how long any storage figure would last under a different demand pattern.

Sources: Water Resources Agency — reservoir storage, allocation and drought response↗ · Taipei Times↗ · Central News Agency / Focus Taiwan↗

What this does not establish

  • Reservoir storage is reported as an operational statement on a date. It is not a standing property of the system and does not convert into days of supply under a different demand pattern.
  • How much of the 2026 outcome was infrastructure and how much was the plum rains arriving is not separated in any public account.
  • Industrial water reductions in 2026 were voluntary and self-reported; compliance was not independently measured.
  • The dependence of treatment and pumping on grid supply is documented in general terms, not quantified for any specific facility — and this module publishes no facility detail.

Medical continuity and pharmaceutical dependence

As of 2026-09

Taiwan's health system is comprehensive, universally insured and concentrated in the same western corridor as everything else on this surface — and it is import-dependent at the molecule. Taiwan produces roughly 16 per cent of its own active pharmaceutical ingredients, with under 15 per cent of domestically supplied drugs using domestic APIs; global API production is concentrated in China and India. In March 2026 the government announced a four-year National Pharmaceutical Resilience programme for 2026–29 worth about NT$24bn — NT$13.16bn from the Ministry of Economic Affairs, NT$8.04bn from the Ministry of Health and Welfare and NT$2.8bn from the Nuclear Safety Commission — with a stated shift from just-in-time to just-in-case procurement and a target of domestic production for at least 50 critical drugs. As of this review the programme's appropriation had not passed the Legislative Yuan, which is the difference between a policy and a capability, and this module keeps it on the announced side of that line. Hospital continuity itself depends on power and water, both of which are separate objects here. Vigil publishes no medical stockpile level, no surge-capacity estimate and no continuity plan, because none is public and estimating one would be inventing it.

What this does not establish

  • Medical stockpile levels, hospital surge capacity and clinical continuity plans are not published, and this object estimates none of them.
  • The domestic API share is a policy-document figure rather than a measured statistic, and different official statements give it slightly differently.
  • Which 50 critical drugs the programme targets has not been published as a list.

What would change this

  • Do gas holdings track the stepping requirement, or lag it?Variable — reported days of gas cover against the requirement schedule (11 days in 2025, 14 in 2027) and the storage-capacity schedule (20 days in 2025, 24 in 2027). Observable — ministerial statements to the Legislative Yuan, MOEA Energy Administration publications, and completion of new storage capacity. Watch each fuel against its own target rather than in aggregate; gas is the binding case because it has the shortest cover and cannot be warehoused. Why it matters — the gap between a requirement and a holding is the only part of energy exposure that is publicly measurable at all.
  • Does any reactor restart move from filing to regulatory decision?Variable — the status of restart applications before the Nuclear Safety Commission. Observable — a docketed regulatory decision, not a political statement or a referendum result. Direction that would matter — approval with a construction and fuel timeline attached. Why it matters — nuclear generation has been zero since May 2025; on published timelines no restart is possible before roughly 2028, so anything sooner would mean the timeline itself had changed.

Fuel reserves, and why they are not one number

As of 2026-08

Energy is the sharpest civil dependency, and the reserves are not interchangeable. Natural gas carries a security-stockpile REQUIREMENT on importers that steps 7 days (2019) → 8 (2022) → 11 (2025) → 14 (2027), with a parallel storage-CAPACITY requirement stepping 15 → 16 → 20 → 24 days; the economics minister stated holdings above 11 days on 5 March 2026. Coal is held against a statutory floor of about 30 days, with Taipower reporting holdings above it. Oil carries a 90-day statutory reserve split 60 days on refiners and importers and 30 on government, with more than 100 days reported in March 2026. Gas is the binding case: it is the largest single share of generation, it has the shortest cover, and it cannot be warehoused the way coal and crude can. These are four different kinds of number — a requirement, a capacity, an operator statement and a statute — and Vigil publishes no combined "days of energy" figure, because the fuels serve different plant and cannot be substituted on the timescale of a disruption. Nuclear generation has been zero since the last reactor shut in May 2025; restart filings are before the regulator rather than in progress, and a 2025 referendum on restart failed to meet its participation threshold. Reported policy responses through 2025–26 are expanded storage, supplier diversification and examination of regional storage arrangements. The module tracks published requirements and stated holdings; it publishes no terminal, facility or routing detail.

The grid, and a hardening programme measured against its own targets

As of 2026-08

Taiwan's grid was built centralised — large generation on the west coast serving demand concentrated on the same plain — which is efficient and has poor resilience characteristics. The March 2022 "303" failure, which cut supply to some 5.49 million households and halted semiconductor, cement and petrochemical plants, made that a political question rather than an engineering one. Taipower's answer, announced in September 2022, is the Grid Resilience Strengthening Construction Plan: NT$564.5bn over ten years, of which NT$437.9bn is distributed-grid work, NT$125bn is reinforcement and NT$1.69bn is protection, with dedicated microgrids intended to serve the science parks directly rather than across the interregional network. It is a committed programme at roughly its mid-point, and Vigil records it as that. None of the major national failures of recent years was hostile in origin; what they demonstrated is the cascade — grid disruption reaching water pumping and treatment, transport and industry within hours — which is why the water and communications objects on this surface both name power as a dependency. Resilience work is described here at programme level only.

What this does not establish

  • Holdings on any given date are not published for any fuel. What exists are periodic ministerial and operator statements, recorded here as statements rather than as measurements.
  • Coal holdings are reported by the operator that holds them and are not independently audited.
  • How much of the NT$564.5bn grid programme has been built, as against committed, is not reported at a granularity that would let progress be measured against the ten-year plan.
  • Nothing public establishes how gas cover would behave under a demand pattern other than the normal one, and this object constructs no such estimate.

Resilience measures — announced kept apart from in place and tested

What would change this

  • Are cable incidents outpacing repair capacity and redundancy?Variables — annual incident count against the four-year average of seven to eight; time to restoration; and the share of incidents in which a cause is legally established. Observable — MODA's annual damage analysis, prosecutions, and regional cable-ship availability. Why it matters — restoration time is set by vessel availability rather than by repair difficulty, so the constraint sits outside Taiwan entirely. Attribution is treated cautiously in every case, and an unresolved incident is recorded as unresolved.
  • How much backup capacity is actually in service, as against announced?Variable — satellite and microwave capacity carrying live traffic, and the number of non-geostationary terminals operating rather than sited. Observable — MODA and NCC reporting, new inter-island cable completions, and carrier participation in regional systems. Why it matters — redundancy is not immunity: every backup path is materially lower capacity than the cable it stands in for, and only capacity in service changes an exposure.
  • Does public warning stop depending on the paths a crisis would remove?Variable — whether alert content is self-sufficient on cell broadcast and SMS alone. Observable — the design of alerts issued in the next urban-resilience cycle, after the August 2026 drills sent recipients to look up guidance online while data was throttled. Why it matters — this is the one exercise finding on this surface that identified a concrete, fixable design fault rather than a capability question, so whether it is fixed is a direct test of whether exercises feed back into policy.

Undersea cables, incidents, and the repair constraint

As of 2026-08

Taiwan reaches the world through 15 international submarine cables, with 10 domestic cables serving the outlying islands, all designated national critical infrastructure as of end-February 2026. The Ministry of Digital Affairs records an average of seven to eight incidents a year in Taiwan's coastal waters over four years, with anchor dragging accounting for an average of 38.3 per cent; 2025 produced seven, of which at least three nearshore incidents were anchor-related and six offshore cables were disrupted by submarine landslides after an end-of-year earthquake. The attribution discipline matters more here than the counts. Four claims are kept apart: damage occurred; interference is suspected; interference is established; a state is responsible. Two 2025 cases reached the third of those — criminal convictions over a Togolese-flagged vessel and a Chinese fishing vessel — and none reached the fourth. Cable damage is common worldwide in shallow, busy water, which is exactly what makes deliberate damage cheap to attempt and hard to prove; Vigil treats individual incident attribution as unresolved unless authorities state otherwise. The rate-limiting factor on restoration is not the difficulty of a repair but the availability of regional cable-repair vessels, which are few and commercially scheduled. No route, landing point or capacity share is published here.

Redundancy — satellite, microwave and the domestic path

As of 2026-08

Taiwan's connectivity response is a layered one rather than a single substitute. The Ministry of Digital Affairs has opened 19 satellite frequency bands and admitted multiple constellations, deployed non-geostationary satellite terminals at key government locations, subsidised expansion of microwave capacity, and funded new inter-island cable systems — Taiwan–Matsu No. 4, Taiwan–Penghu No. 4 and Penghu–Kinmen No. 4 — alongside encouraging domestic carriers into regional systems such as SJC2 and Apricot to reduce single-path reliance. Legislative amendments in July 2026 eased market entry for satellite communications providers. The discipline this section applies is that redundancy is not immunity: every one of these paths is materially lower capacity than the cable it backs up, and the figure that changes an exposure is capacity IN SERVICE, not bands opened, terminals sited or contracts signed. Vigil records what has been announced, what has been reported as built, and keeps those two columns apart.

Public warning, and what the August 2026 drills showed about it

As of 2026-08

Taiwan's public-warning layer is deliberately built on the most robust bearers it has: cell broadcast for disaster and air-raid alerts, voice and SMS, and the 110 and 119 emergency numbers. The August 2026 urban-resilience exercises tested that assumption directly by degrading everything else. On 10 August in the central region and 13 August in the north, the National Communications Commission reduced 4G and 5G mobile data to roughly one per cent of capacity for about 17 million people — some 73 per cent of the population — for a scheduled half-hour, while deliberately keeping voice, SMS, emergency calls and cell-broadcast alerts running. What the exercise established is what was rehearsed and what stopped: reporting from the central wave records that retailers could not take electronic payment, that official websites and online services were unreachable, and — the finding that matters most for this object — that the national alert itself directed recipients to look up evacuation guidance online, in the condition the drill had just created. A legislator publicly questioned the exercise's legal basis, objectives and success criteria. Vigil records that the drill ran, its published scope, and the reported effects. It does not conclude that the warning system works or that it does not: an exercise establishes what was tested, and the design flaw the drill exposed is a finding about the message, not a measurement of the system.

Cyber disruption, as a continuity question

As of 2026-07

Taiwanese government and infrastructure networks report sustained probing and intrusion attempts at a volume among the highest stated by any government. The civil-resilience concern is not espionage but continuity: the systems whose disruption a population would feel are payments and banking, utilities, transport scheduling and public communications, and those are the systems this object tracks. Public reporting is uneven, official figures are counts of attempts rather than of effects, and attribution is contested; this module reports officially stated figures as stated figures and grades them accordingly. It draws no line from the existence of a capable adversary organisation to responsibility for any particular incident — the PRC's post-2024 information-support and cyber arms are described in the Force Atlas as institutions, and an institution's existence is not evidence about a campaign.

Sources: Taiwan Presidential Office and Executive Yuan statements↗ · Reuters — Taiwan and China coverage↗

What this does not establish

  • Satellite and microwave capacity actually carrying traffic is reported in outline rather than measured, so the size of the fallback is not established.
  • Attribution is unresolved for most cable incidents and established for two 2025 cases only. No incident has been attributed to a state.
  • The August 2026 drill degraded data for a scheduled half-hour by agreement with carriers. It establishes what depended on data, not how any system behaves under unplanned or sustained loss.
  • Reported effects on payments and services during the drill come from contemporaneous reporting rather than from an official after-action measurement.
  • Official cyber figures count attempts rather than effects, and no public series measures service disruption actually caused.

How conditions reach this

What would change this

  • Do arrivals or war-risk terms change before anything else does?Variables — vessel calls and cargo throughput at the western ports, and whether Taiwan or its approaches appear in the Joint War Committee's Listed Areas. Observable — Taiwan International Ports Corporation throughput reporting, and the Listed Areas themselves, which are published and binary. Why it matters — commercial behaviour moves before a physical constraint does; insurance listing and sailing decisions are the earliest civilian-visible indicators on this surface, and they are observable without any access to what either government intends.
Each figure carries the date it is for, the basis it rests on and its own confidence grade. Nothing on this page totals or compares across two vintages, and a requirement, a capacity, an operator statement and a statute are never presented as the same kind of number.

What constrained access would mean for civilian supply

As of 2026-08

The scenario most often discussed is the least well understood. A quarantine, inspection regime or blockade would not primarily be a military event for civilians; it would be a logistical and commercial one — sailings deterred or delayed before they were stopped, war-risk insurance repricing or withdrawing, and arrivals of fuel, food and industrial inputs thinning rather than ceasing. Taiwan's exposure is structural rather than tactical: an island importing almost all of its energy and roughly seven-tenths of its calories has limited ability to substitute domestically at any speed, and the substitution that exists is agricultural and measured in seasons. Vigil states this as exposure, not prediction. It publishes no threshold, no sequence, no duration and no exhaustion date, and it does not treat such an action as expected — the costs to the actor undertaking it are part of the same analysis and are assessed in the module's Economy and Operations sections.

Ports, arrivals and distribution

As of 2026-08

Everything in the paragraph above reaches households through a small number of ports. Kaohsiung handled about 46 per cent of Taiwan's cargo tonnage and roughly 65 per cent of its container throughput in 2023, with Taichung, Taipei and Keelung taking most of the balance; of some 39,650 inbound vessel calls that year, 39 per cent went to Kaohsiung and 30 per cent to Taichung. That concentration is an efficiency property of a trading economy and a dependency property of a besieged one, and it is the same fact either way. What the concentration does NOT establish is a failure mode: Vigil publishes no berth, terminal or handling detail, and states no view on how throughput would redistribute under constraint, because nothing in the public record establishes it. Physical access is this section's question; what reduced throughput would cost is the Economy section's, and the two are cross-linked rather than duplicated.

Food supply, and what the self-sufficiency rate does not say

As of 2026-08

Taiwan's comprehensive food self-sufficiency rate was 30.3 per cent on a calorie basis in 2023 — an eighteen-year low, driven substantially by reduced rice production after irrigation was curtailed during drought. The figure is routinely misread. It measures domestic production against domestic consumption in a normal year; it is not a stock, not a days-of-supply figure, and not a statement of what could be grown under constraint, when planting choices, feed imports and calorie composition would all change. Rice is the exception worth naming: it is the largest single domestic calorie source and the one staple held in public reserve. Vigil publishes no reserve tonnage, no ration arithmetic and no estimate of how long any food stock would last, and it notes that the binding constraint on food is the same as on fuel — arrival, not production.

Sources: Ministry of Agriculture — food balance sheet and self-sufficiency rate↗

What this does not establish

  • Food and fuel stocks held commercially rather than under statute are not published, so nothing here supports a days-of-supply figure for either.
  • How port throughput would redistribute under constraint is not established in any public source, and this object states no view on it.
  • Whether commercial shipping would continue to call under an inspection or quarantine regime is unresolved; it has never been tested for main-island traffic.
  • Port shares are 2023 figures, the newest full-year breakdown published. The concentration is stable year to year; the precise shares are not current.

Resilience measures — announced kept apart from in place and tested

What would change this

  • Is measured public confidence holding as the foundation the rest rests on?Variables — polling series on confidence in institutions, in the armed forces, and in the reliability of external support; and personal-preparedness measures. Observable — established academic and polling series with published methods, read as trend lines rather than as single readings. Why it matters — it is the declared target of sustained information pressure and the input every other resilience measure assumes. A change in the trend would not by itself establish that an information operation caused it, and this question does not treat it as such.

Information pressure — attribution, channel and audience, kept apart

As of 2026-08

Taiwan is among the most heavily targeted societies in the world for external information operations, and the through-line in published analysis is consistent: undermining confidence in the government, in the armed forces, and above all in the reliability of United States support. The analytical discipline this object exists to hold is that an information operation has at least four separable properties — attribution, channel, audience and observable effect — and that public reporting establishes them to very different standards. Attribution to a state is established in some cases and asserted in many; channels (platform, broadcast, personal networks, commissioned local content) are often documented; audiences are usually inferred from content rather than measured; and EFFECT is the property least often established at all. This module therefore does not maintain a general "propaganda" bucket, does not count narratives as if counting them measured reach, and does not treat the existence of the PRC's post-2024 information-support and cyber structures as evidence of responsibility for any particular campaign. Where the effect of an operation is not measured, the record says it is not measured.

Public trust, and what is actually measured about it

As of 2026-08

Every other resilience measure on this surface rests on public confidence — in institutions, in the armed forces, and in whether external support would arrive — and that confidence is the declared target of the pressure described above. It is also the one thing in this file that is routinely measured, by academic and polling series with published methods, which makes it the most tractable observable here and the one most often over-read. Taiwan's countermeasures are studied internationally: rapid government rebuttal mechanisms, a strong civil-society fact-checking sector, and media-literacy education embedded in schooling. What none of that establishes is efficacy. A society that is heavily targeted and retains high institutional confidence may be resilient, or may be targeted ineffectively, or may be measured with instruments that miss the effect; the published record does not separate those, and Vigil does not either. The pressure is chronic rather than episodic, which makes this a question about a trend line rather than about any incident.

What this does not establish

  • The observable EFFECT of information operations on Taiwanese opinion is not established by any public measurement, and no claim here rests on one.
  • Attribution to a state is established for some campaigns and asserted for many. The two are not merged.
  • Audience reach is generally inferred from content rather than measured.
  • Whether Taiwan's countermeasures work is not established: a heavily targeted society with stable institutional confidence is consistent with effective defence, with ineffective attack, and with instruments that miss the effect.

Civil defence, drills and published public guidance

As of 2026-08

Civil-defence reform has expanded since 2022: an all-of-society resilience committee at presidential level, conscription restored to one year from 2024, and — the most visible public artefact — a civil-defence handbook, "In Case of Crisis: Taiwan's National Public Safety Guide", issued by the All-out Defense Mobilization Agency in September 2025, illustrated, 29 pages across 18 topics, distributed to households and published online with links to shelter-locator applications. Its household guidance is a one-week supply and a prepared go-bag. The 2026 Han Kuang exercise, 5 to 14 August, folded the urban-resilience component into the military exercise for the first time as a genuine whole-of-society mobilisation: dispersal of weapons production, conversion of civilian factories, protection of maritime supply routes, naval–coast guard coordination, roughly 20,000 reservists mobilised, and operation under deliberate mobile-network degradation across fourteen administrative regions. Local governments activated emergency operations centres and ran drills at medical stations, relief centres and supply distribution hubs, in Kaohsiung and Pingtung on 6–7 August and New Taipei and Yilan on 12–13 August. Officers were reported to be working without the advance scripts used in previous years, which made adaptive command part of what was tested rather than a stated aim. Vigil records that the exercise ran and what it set out to test, and publishes no assessment of how it performed — the distinction between what an exercise rehearses and what it demonstrates is the whole discipline of this object. Progress is genuinely contested: analysts and Taiwanese commentators question training quality, reserve readiness and public engagement, and surveys consistently show modest personal preparedness. No shelter location, capacity or emergency procedure is published here.

Reserve reform, and the institution that administers it

As of 2026-06

Reserve mobilisation in Taiwan runs through civilian local government at least as much as through military channels, which is the problem the All-out Defense Mobilization Agency was created in January 2022 to solve, by merging the All-out Defense Mobilization Office with the Armed Forces Reserve Command under one agency reporting to the Ministry of National Defense. Two measurable changes have followed. From 2026 all reserve call-ups are standardised at 14 days, replacing a 5-to-7-day programme and eliminating a parallel dual-track arrangement; and the alignment rate between a reservist's duty at discharge and their reserve assignment was reported to the Legislative Yuan on 22 June 2026 at about 93 per cent. Both are administrative facts and both are the right kind of indicator for this file: dated, published and checkable. Neither is a measure of capability. A 14-day standard says how long training is, not what is taught or how well; a 93 per cent alignment rate says reservists are being matched to their former roles, not that the formations they would join are manned, equipped or ready. Vigil publishes no reserve strength, no call-up capacity, no mobilisation timeline and no readiness assessment, and the agency does not publish them either.

The standing cost of living inside a pressure system

As of 2026-07

The least visible cost in this file is the one already being paid. Living inside a sustained pressure system — near-daily reported military activity, chronic information operations, conscription extension, recurring crisis coverage — carries measurable social costs: emigration decisions, investment hesitancy, polarisation over defence policy, and a documented public fatigue that can shade into either complacency or fatalism. It is recorded deliberately, because coverage built only from scenarios misses the pressure people are actually under, and because fatigue is the mechanism by which every preparedness measure above quietly loses participation. Vigil states this as an observed pattern in published research and commentary, not as a measured quantity.

Sources: Brookings Institution — Taiwan and East Asia analysis↗

What this does not establish

  • Reserve strength, call-up capacity, mobilisation timelines and readiness are not published by any Taiwanese body and are not estimated here.
  • No after-action assessment of Han Kuang 42 has been published, so what the exercise demonstrated — as against what it rehearsed — is not established.
  • Training quality under the 14-day standard is contested in commentary and not measured in any public series.
  • Local-government participation is reported as having occurred rather than assessed for adequacy.
  • The social costs of prolonged mobilisation are an observed pattern in published research, not a quantity this module measures.

How to read this file

As of 2026-09

Four kinds of statement appear on this surface and they are not interchangeable. A REQUIREMENT is what law or regulation obliges someone to hold or do. A TARGET is what a programme intends, and until an appropriation passes and a thing is built it stays a target. An OBSERVED FIGURE is what an operator or ministry has stated it actually held or did, on a date. An EXERCISE FINDING is what was rehearsed and what was reported to have happened during the rehearsal — never a measure of wartime performance. Where two of these exist for the same system, both are given with their vintages rather than reconciled; where sources disagree, the disagreement is preserved rather than averaged. Nothing here is aggregated into a resilience score, a preparedness index or a days-of-supply total, because no such figure can be constructed honestly from stocks that are not interchangeable and measures that are not commensurable.
